„ Curve Sampling Status Flag
When sampling general trend graph or X-Y chart, the curve sampling status flag will be set to be ON
(Bit 0 ~ Bit 3 is set to ON). After sampling operation is completed, the curve sampling status flag will be
OFF.
„ Curve Clear Status Flag
When clearing general trend graph or X-Y chart, the curve clear status flag will be set to be ON (Bit 8 ~
Bit 11 is set to ON). After clear operation is completed, the curve clear status flag will be OFF.
